Physical, chemical properties and antioxidant capacity of the pomegranate hp "molar" during the developement of the result.
A caracterização das transformações que ocorrem durante o desenvolvimento do fruto possibilita identificar o período em que os frutos reúnem o maior número de características que expressam a qualidade do fruto para a comercialização in natura ou industrial. Assim o objetivo deste estudo foi quantificar as mudanças nas características físicas, físico-químicas e atividade antioxidante do suco e rendimento de óleo e amido da semente da romã cv.‗Molar‘, durante o desenvolvimento do fruto. O delineamento experimental foi o inteiramente casualizado, cujos tratamentos foram constituídos pela idade dos frutos (10, 20, 30, 40, 50, 60, 70, 80, 90 e 100 dias após a antese), com quatro repetições constituídas por cinco frutos por parcela totalizando 20 frutos por tratamento. Após a colheita os frutos foram transportados para o Laboratório de Análises de Alimentos da Universidade Federal de Campina Grande (UFCG), Campus de Pombal-PB, onde foram realizadas as análises físicas, físico-químicas, atividades antioxidantes do suco. A análise de rendimento de óleo e amido das sementes foi realizada pelo Laboratório Instituto Tamanduá, Patos-PB. Ao longo do desenvolvimento ocorreram alterações nas características físicas, físico-química, atividade antioxidante e de rendimento do óleo e amido da semente. Romãs cv. ‗Molar‘ tiveram uma massa de 200 g, formato oblíquo, no que diz respeito a variável volume do fruto constatouse aumento até os 100 dias de idade. Os frutos apresentaram alteração na coloração da casca a partir dos 50 dias sendo que aos 90 dias os frutos apresentaram coloração amarelo-alaranjado. No suco houve evolução da cor para um rosa avermelhado com redução da
intensidade com o avanço da idade. Para as análises químicas constatou-se redução da
acidez titulável (AT) a partir dos 80 dias enquanto que no mesmo período houve aumento no teor de SS, SS/AT, açúcares totais e redutores e vitamina C com o desenvolvimento do fruto. No que diz respeito aos pigmentos, fenólicos, antocianinas e carotenoides, verificou-se que com o aumento da idade dos frutos, a concentração de fenólicos diminui linearmente, enquanto que a concentração de antocianinas ocorreu um aumento polinomial atingido concentração máxima aos 90 dias apresentando-se uma coloração avermelhada, ao mesmo tempo os carotenoides apresentaram a menor concentração aos 90 dias de idade com valor de 0,18 µL/100 mL-1 . O tratamento de 90 dias foi o que apresentou a maior capacidade antioxidante com valores de 3501,00 g.polpa.100 mL de DPPH e 10546,52 uM Trolox/g polpa para os métodos DPPH e ABTS respectivamente, revelando alta atividade antioxidante dos frutos nesse período. Rendimento do óleo e amido da semente alterou-se significativamente durante o desenvolvimento do fruto da romã. Houve acréscimo de 11,57% no rendimento de óleo dos 60 para os 100 dias após a antese, em contra partida ocorreu um decréscimo no rendimento de amido tendo o menor rendimento nos frutos colhidos aos 100 dias (12,97%). Diante dos resultados obtidos observa-se que os frutos colhidos aos 90 dias reuniram o maior número de características de qualidade, que juntas possibilitaram identificar a idade na qual os frutos encontram-se aptos a serem colhidos, nas condições de cultivo das Várzeas de Sousa, PB.The characterization of the transformations that take place during the fruit development of the
result makes possible to identify the period in which the results join the biggest number of
characteristics that express the quality of the result for the marketing in natura or industrial.
So the objective of this study quantified the changes in the physical characteristics, chemicalphysically
and antioxidant activity of the juice and profit of oil and starch of the seed of the
pomegranate hp.'Molar‘, during the development of the result. The experimental delineation
was it completely casualizado, whose treatments were constituted by the age of the results
(10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 days after the antese), with four repetitions
constituted by five results by piece totalizing 20 results for treatment. After the harvest the
results were transported for the Laboratory of Analyses of Foods of the Federal University of
Big Prairie (UFCG), Campus Of - PB, where the physical analyses were carried out,
chemical-physically, antioxidant activities of the juice. The analysis of profit of oil and starch
of the seeds was carried out by the Laboratory Institute Anteater, - PB. Along the
development alterations took place in the physical characteristics, chemical-physically,
antioxidant activity and of profit of the oil and starch of the seed. Pomegranates hp. ‗Molar‗
they had a mass of 200 g, oblique format, what concerns variable volume of the result
increase was noted up to 100 days of age. The results presented alteration in the coloration of
the bark from 50 days being that to 90 days the results presented coloration orangey-yellow.
In the juice there was evolution of the color for a rose reddened with reduction of the intensity
with the advancement of the age. For the chemical analyses (AT) noted reduction of the
acidity titulável from 80 days whereas in the same period there was increase in the tenor of
SS, SS/AT, total and reducing sugars and vitamin C with the development of the result. What
concerns the pigments, fenólicos, antocianinas and carotenoides, happened what with the
increase of the age of the results, the concentration of fenólicos reduces linearly, whereas the
concentration of antocianinas took place an increase polinomial when the very concentration
was reached to 90 days when a reddish coloration is showing up, at the same time the
carotenoides presented the least concentration to 90 days of age with value of 0,18 µL/100
mL-1. The treatment of 90 days was what pulp presented the biggest antioxidant capacity with
values of 3501,00 g.polpa.100 mL of DPPH and 10546,52 a Trolox/g for the methods DPPH
and ABTS respectively, revealing high antioxidant activity of the results in this period. Profit
of the oil and starch of the seed was altered significantly during the development of the result
of the pomegranate. There was addition of 11,57 % in the profit of oil of the 60 for 100 days
after the antese, in against departure a decrease took place in the starch profit having the least
profit in the results gathered to 100 days (12,97 %). Before the obtained results it is noticed
that the results gathered to 90 days joined the biggest number of quality characteristics, which
boards made possible to identify the age in which the results are suitable to be gathered, in the
conditions of cultivation of the Meadows of Sousa, PB

Physical activity recommendations for cancer prevention and control: a Brazilian consortium
Objective: This article describes the development process and summarizes the results of the Brazilian physical activity recommendations for cancer prevention and control, which was prepared to support health-care professionals.
Material and Methods: These recommendations were elaborated considering: (i) the effect of physical activity on cancer prevention in the general healthy population; and (ii) on all-cause and cancer-specific mortality in cancer survivors. The process of preparing the recommendations was systematized, transparent and reproducible, following the recommendations of the appraisal of guidelines for research and evaluation (AGREE-II). We appraised the certainty of evidence for breast, prostate, colorectal and lung cancers, which are among the most frequent in Brazil, using the grading of recommendations, assessment, development and evaluations (GRADE) approach.
Results: Regarding the risk of cancer, we found high certainty of evidence supporting the association between moderate-to-vigorous physical activity and lower risk of breast and colon cancer, moderate certainty of evidence for lung cancer and low certainty of evidence for prostate and rectal cancer. We found moderate certainty of evidence supporting the association between moderate-to-vigorous physical activity and reduction of all-cause and cancer-specific mortality from breast, colon and rectal cancer, and cancer-specific mortality from prostate cancer, when physical activity was performed after the disease diagnosis. We found low certainty of evidence for the association between physical activity and lung cancer mortality. Based on our findings, physical activity recommendations were proposed, including a step-by-step guide to support health-care professionals when recommending physical activity for all adults (including elderly people), with or without a diagnosis of cancer.
Conclusion: Our recommentations may be useful to support health-care professionals counselling for physical activity, which contribute to reductions in physical inactivity in the general population and in the growing population of cancer survivors
